In many river basins, notwithstanding the WFD’s imperative of Using Sediment As a Resource (USAR) is a cause-effect consideration and cooperation at river basin scale, project funded by the European Union’s the planning of measures is often still dominated by sectoral Interreg 2seas Programme (2016-2020). political, administrative and economic interests and restrictions. Partners from the Netherlands, Belgium, Obtaining the required level of cooperation between the France and the United Kingdom are working different responsible authorities, the Government and between together to promote a resource-efficient the States remains difficult. As a consequence, management approach based on the potential for re-use decisions are often taken out solely from a single State or of dredged sediments.

09.00 - 15.00 Excursion to Ston and Mali Ston Located in the Dubrovnik-Neretva county, the bay of Mali Ston has been famous for seashell cultivation since the days of the Roman Empire as it hosts the largest oyster cultivation facilities in the Adriatic. During the visit to the bay, researchers from Dubrovnik University will explain about the water conditions for cultivating oysters, and you will get the chance to taste oysters (and some local wine). There is also the possibility to visit the Walls of Ston, a series of defensive stone walls, originally more than 7 kilometres long, that surrounded and protected the city of Ston, in Dalmatia, part of the Republic of Ragusa, in what is now southern Croatia. Their construction was begun in 1358. Today, it is the second-longest preserved fortification system in the world. The Walls of Ston were known as the “European wall of China” Further, you can visit the salt yards - Solana Ston. Salt has been harvested in Ston since Roman times and these particular salt pans have operated in much the same way for over 700 years. An introductory video explains the process, after which you can take a walk around the evaporation pans and the factory building. Salt is gathered between late July and September.

And if you like to have some coffee or lunch, there are several cafes and restaurants in Mali Ston where you can go to.

Included in the tour are: bus transport to/from Mali Ston, boattour in the bay, oyster tasting and a glass of wine (on board). Other costs (museum visit, coffee, lunch) are at your own expense.

SedNet is the European network which aims to incorporate sediment issues and knowledge into European strategies to support the achievement of good environmental status or potential and to develop new tools for sediment management. Its focus is on all sediment quality and quantity issues at the river-sea system scale, ranging from freshwater to estuarine and marine sediments. SedNet brings together sediment professionals from science, administration, industry and consultancy. It interacts with the various networks in Europe that operate at national or international level or that focus on specific fields (such as science, policy making, sediment management, industry, education). Special attention was devoted in recent years to the integration of sediment management in the Water Framework Directive implementation process, and particularly in the River Basin Management Plans.
